This product is built with a predetermined actuator spring suitable for at, or slightly above factory boost levels. The actuator can be assembled with a stiffer spring upon request. Please contact us directly concerning this process

It is designed and built with the intention of increasing the boost output of a turbocharged system. We cannot guarantee compatibility with all applications, nor the ability to increase the boost output beyond a level that is within the parameters set by the engine-management-system of the given vehicle at the time of installation, whether that system is factory or aftermarket.

Forge Motorsport nor any of it's authorized distributors can assume any responsibility for any adverse effects resulting from the installation and tuning of this product onto a vehicle whose engine-management-system, whether factory or aftermarket, is not capable of allowing for the desired level of adjustment. While Forge Motorsport is happy to supply you with an actuator capable of holding boost beyond that of your factory unit we are in no way capable of knowing nor suggesting that your vehicle's engine or related systems are capable of supporting or surviving the stresses of such elevated boost pressure.

Almost Perfect

Installation was a snap, build quality and finish are top notch, although I'd prefer something a little less blingy, maybe black anodized would be nice. I think the 7# spring option is pointless, that's factory weight and you'll see no advantage from using it. With the 10-15# spring, however, it worked flawlessly. My only real issue is the size of the boost line fitting, it's huge, easily twice as big as every other fitting on the boost control system. You can get a factory sized hose over it, but it'll take some persuasion and the clamp won't fit.

rock solid boost

I purchased this wastegate actuator a few months ago and all I can say is wow I have a 2003 wrx with a stage 2 setup with about 307hp at the wheels and 18.7psi between this and my boost controller I experience no creep surge spikes etc. It's rock solid and I love it.
